Best,

My Asus ROG came with 1 HD in raid, it drove me nuts until I found out.

Funny thing you guys mentioned that. I kinda missed this item in the firmware - "Storage". I was looking there, but couldn't see.

I get there and switch to AHCI, saved changed and reboot firmware. I was shocked - I cannot see this item any more. I reboot to Windows and sure enough - it won't boot. I tried few tricks I know trying to repair boot, but no luck. I reset the firmware - to be able to see "Storage". Then I saw it, put back to RST and boot into Windows.

Now I will try to change to AHCI, but the right way lol. Once in a while I like to do experiments, you know :-)

Just booted into Debian. Thank you very much guys for your help.

I did not realize that Lenovo for some weird reason will use RAID setup even with a single SSD. Kinda weird choice, but now I know what to do.

Again guys, thank you for your help. You saved me.

P.S. I was shocked that touchpad is working. I have read manuals how to turn it on and had them handy, but looks I don't really need.
P.P.S. I was even more shocked that touch screen is wirking. After reading all that comments that touch screen is not great in Debian - IDK, I have nothing complain about.
P.P.P.S. I will need to figure out how to increase scale. I'm older guy and my eyes are not great as they used to be. So, I'll need to do smth with screen scaling.

I got a new DELL Inspiron 3880 desktop with windows, when i continued with Debian net installer i could not see any disk out there apart from USB drive i.e. the bootable drive.
After updating BIOS settings (Disable RAID) the SATA Segate HD and Samsung 970 NVME SSD both are visible, while the installation disk selection page.
Debian installation also completed fine but Grub Dual boot could not boot both the OS now at one go. If i enable RAID: the windows boots fine but Debian fails, if disable Raid: (switch to AHCI) Debian works fine and windows fail so sort of stuck up :(

I can try windows install with RAID off and AHCI which could load both but is it the only and best alternative ?

Appreciate any experts help or comments...

Windows needs to be set to ACPI before changing to it from RAID in UEFI /BIOS settings. There are a few guides on the webz. Not sure if you can change it after. May have to set it back to RAID then change Windows settings then subsequently back to ACPI again.

Also, it's normal forum etiquette to start a new thread for a new issue rather than tacking on to an existing one.

I am able to resolve the issue of disks not getting listed in Debian install screen by changing the RAID to AHCI via BIOS settings.

Though there are few ways to fix windows after above change but i did fresh windows install over SSD after new bios settings and now both OS are working fine. Debian is installed in HDD partition.
